Answer:
SU = 16
Step-by-step explanation:
SU= 8x
ST = 6x
TU = 4
SU = ST + TU = 6x + 4 = 8x
SU - ST = 8x - 6x = 2x = 4
2x = 4
x = 4/2
x = 2
SU = 8x
SU = 8(2)
SU = 16
Just let every x in f(x) be g(x)
it means:
f(g(x))=(2x^2+5)^2+(2x^2+5)+2
=4x^4+20x^2+25+2x^2+5+2
=4x^4+22x^2+32
Which factors can be multiplied together to make the trinomial 5x2 + 8x – 4? Check all that apply.
(x + 1)
(2x + 1)
(x + 2)
(5x + 1)
<span>(5x – 2)
Solution :
By multiplying (5x - 2) and (x + 2), the given trinomial will be obtain as follow.
</span>(5x - 2) * (x + 2) = (5x * x) + (5x * 2) - (2 * x) - (2 * 2)
= <span>5x^2 + 10x - 2x - 4
= </span>5x^2 + 8x - 4
Yes, the prism having three lateral faces as rectangles is a triangular prism.
Answer:
A) infinitely many solutions
Step-by-step explanation:
2x - y = 8
4x - 2y = 16
simplify the first equation
2x - y = 8
2x = 8 + y
2x - 8 = y
y = 2x - 8
substitute y for 2x - 8 in the second equation
4x - 2y = 16
4x - 2(2x - 8) = 16
4x - 4x + 16 = 16
4x - 4x = 16 - 16
0x = 0
since no matter what x is, 0 = 0, the answer is infinitely many solutions
